Description

(54) DEVICE FOR LOADING AND UNLOADING ..THE LOADS

I

The invention relates to vehicles with devices for loading and unloading goods and can be used for transporting goods on the platform in containers and bins.

A device is known that is equipped with a lever mechanism, made in the form of rotating levers around a machine fixed axis, which is set in motion by two hydraulic cylinders, and which moves a hopper suspended from chains from chassis to ground 1.

The disadvantage of this device is the small effective volume of the hopper. To increase it, it is necessary to increase the height and width of the bunker, which leads to machine instability and difficulties in its operation on roads.

It is also known a device for loading and unloading piece goods, mounted on a vehicle frame, comprising a platform and a main ram for raising and lowering it, connected by a rod to the front of the platform (2.

The disadvantage of this device is low loading-unloading performance.

The purpose of the invention is to improve the performance of loading and unloading.

For this, the device is equipped with guides mounted on the vehicle frame, a carriage mounted for movement in directions TSI, and hingedly mounted in the rear part of the platform, mounted for rotation in a vertical plane by means of additional power cylinders mounted on the platform the main ram is rigidly coupled to the carriage.

FIG. 1 shows the proposed device; in fig. 2 is the same, top view, in FIG. 3-9 - position of the device at different moments of loading.

The device comprises a platform I, hung on the rod of the main power cylinder 2 mounted on the carriage 3, having the ability to move on the rollers 4 along the guides 5 mounted on the frame

vehicle 6. In the rear part of the platform 1 there are rotatable in the vertical plane of the means of additional power cylinders 7 of the support 8 having rollers 9. The device operates as follows. The empty vehicle 6 feeds a 3-inch stroke to the immersed object (Fig. 3). The supports 8 rotate to contact with the ground (Fig. 4). The means is fed forward by advancing platform 1 (Fig. 5). Lowering the latter (Fig. 6), the mediator is fed in reverse, pushing the platform under the immersed object (Fig. 7). Raising the platform with the load (Fig. 8), means: it moves it towards itself and, having removed the supports, is ready to transport the load (Fig. 9).
